Improvement in evaporating apparatus for manufacture of sugar



UNITED STATES FFIGE.

FRANCIS Gr. BUTLER, OF BELLOIVS FALLS, VERMONT.

Specification forming part of Letters Patent No. 116,803, dated July l1, 1871.

To all whom it may concern:

Be it known that I, F12-.mers G. BUTLER, of Bellows Falls, county ofVindham and State of Vermont, have invented certain new and useful Inuirovement in Apparatus for Making Sugar, Ste., and to enable others skilled in the art to make and use the same I Wi ll proceed to describe it, referring to the drawing,.in which the same letters indicate like parts in each vof the figures.

The nature of my invention consistsin attachin g to an evaporator, constructed as hereinafter described, a tinishingpan, (which corresponds in its use with the teache or battery ofthe kettlerange-commonly in use in the manutacture of canesugan) and connected with the evaporator by an oscillatin g valve operatin g over an opening from the evaporator into the battery, which valve is operated by rods or levers; reaching to each side of the evaporator or battery, thus making it convenient for the operator to move the valve from Whichever side of the evaporator or battery h e may be, and ren d erin g it easy to let out ch arges or batches of clarified and condensed saceharine iiuids from the evaporator into the battery, Where it may easily be finished for sirup or sugar.

In the accompanying drawing, Figure l is a top or plan view of this pan. Fig. 2 are end-section views.

c is the bottoni of the pan. l) are partitions or corrugations ot' the same length as the Width ot' the bottom sheet c. These partitions or corrugations are formed in the common Way. c are liarin g sides, forme d at an an gle of about forty-five degrees with the bottom, and having a lip or lan ge projection, d, which laps onto and is secured to the under side of the bottom a. e are scumarresters arranged between a part or all of the partitions or corrugations. The lower edges extend onto the bottoni about one-fourth of its Width, andare tted and secured Vto the llarin g sides and extending nearly to the top or outer edge thereof, thus forming elevated compartments upon the sides for arresting and holding the sonni until removed. j' is a discharge-nozzle or opening. g is a finishing or sugaring-off pan extending from one end ot' the evapora-tilig-pan, its bottom being of the same level with the bottom of the evaporating-pan. h is a passage from the evaporating-pan into the finishing-pan g. This passage lzI is opened and closed by an oseillating valve-plate, t, hinged to the partition j near the bottom and just one side of the passage, and is operated from one or both sides of the pan by means of the rod or rods k attached thereto so as to pivot near its upper edge.

To partially recapitul ate: The battery consists of a plain-bottomed pan, of the same Width and level at the bottom as the evaporator to which it is attached, and of any convenient length and depth, both pans having Haring sides. The valve consists of a tlat piece ot' metal, which is secured 'to the end of the evaporator, just outside of the passage-critico, by a bolt at one of the corners near the bottom, and to the upper edge whereof the rods or levers are attached so as to pivot, and by the pulling or pushing ci' which the operator covers or uncovers the opening from the end of the evaporator into the battery.

I believe I have thus shown the nature and construction of this invention so as to enable others skilled in the art to make and use the same therefrom.

What I claim, therefore, and desire to secure by Letters Patent, is-

l. A plain-bottomed battery or finishing-pan, in combination with an evaporator, the pan and evaporator both having fla-ring sides and communicating' directly with each other, the bottoms of both being upon the same level.

2. An oscillating valve, operated by a pivoted rod or rods reaching to 011e or both sides of an evaporatingpan, substantially as shown and described.
